ABSTRACT:
Disclosed is an improved martensitic stainless steel, which essentially consisting of 0.15 to 0.50% of C, 0.01 to 0.50% of Si, 0.30 to 2.0% of Mn, 1.0 to 3.0% of Cu, up to 0.20% of Ni, 13.0 to 17.0% of Cr and 0.02 to 0.10% of N, and the balance being Fe and inevitable impurities. The stainless steel can be easily cold pressed as annealed and acquires a high strength when heat treated. Corrosion resistance of the steel is equal to or better than that of a conventional martensitic steel.
